            Bug ID: 232311
           Summary: [AppSSO] Avoid attempting to display a nil view
                    controller
           Product: WebKit
           Version: WebKit Nightly Build
          Hardware: Unspecified
                OS: Unspecified
            Status: NEW
          Severity: Normal
          Priority: P2
         Component: WebKit Misc.
          Assignee: webkit-unassigned at lists.webkit.org
          Reporter: bfulgham at webkit.org

Crash logs indicate that it is possible for the delegate for an AppSSO authentication to get called after the view has been dismissed (e.g., when a user grows impatient with a slow authentication).

Rather than crashing, we should clean up the session state and make it ready for a new attempt.
